and 52 the split pin for retaining the said coil spring 51 and the collar 51 upon the end of the valve stem 51, as shown upon Fig. 1 of the drawings.

From the foregoing description taken in connection with the accompanying drawings the mode of operation and advantages of the invention will be readily apparent without requiring an extended explanation thereof.

To start the engine the hand of the operator is first applied to one or both of the fly wheels 7 and simultaneously with the force applied to the said fly wheels 7 the piston 2" being at the opposite end of the cylinder 2 from that shown upon Fig. 1 of the drawings, the pressure occasioned by the first explosion presses against the inner end of the said piston 2 and forces the piston into the position shown upon Fig. 1 of the drawings until the inner end of the said piston 2 passes beyond the opening 11 permitting the discharge to pass into the cylinder 10 throughthe pipe 11" shown in dotted lines upon Fig. l and in full and dotted lines upon Fig. 2 of the drawings. The pressure from the said first discharge being equal in the main driving cylinder 2, in the said pipe 11 and in the primary supplemental cylinder 10 forces the said piston 12 carrying the piston rod 14, shown upon Fig. 3 of the drawings to abut against the end of the piston rod 24 carried by the pis ton 23 in the exhaust cylinder 20 from the opening 21 in the said exhaust cylinder 20 of the pipes 21and 21' connecting the said cyl inder 2 and the said cylinder 20 whereby the a said exhaust of the said first explosion is carried into the outer air through the pipe 60 shown upon Figs. 1, 2, 3 and 4 of the drawings. The above mentioned steps of the operation are repeated whenever the engine is in operation.
